Hand touches the shape to feel object, but American scholar thinks through research, and blind person is the most accurate for the object perception of hand size, right
In excessively big object, body form can only be perceived by mobile both hands, i.e., can only obtain the partial information of object simultaneously, need
The processing of countless partial informations is integrated into complete object in the brain, this process is extremely difficult, therefore for some blind
For people, understand that the overall profile of some objects is extremely difficult, needless to say painted out.(4) for drawing between blind person
There are obstacle, no image of Buddha normal person equally corrects the mistake in oneself drawing for the exchange of picture.Based on first-class many apparent
Odjective cause, in art education and disabled persons' education field exist prejudice extensive in this way: blind person is difficult to learn to paint, i.e.,
Make appreciation drawing also can only be in a manner of reading braille, by the drawing of tactilely-perceptible lines protrusion.
The present invention proposes a kind of based on robot progress painting from Blind Persons study instruction to fill up the blank in art education
Experienced method.
Mobile picture-drawing device 100 holds one hand of user, and one finger of user is stretched out and touched from picture-drawing device
200 contact of screen.User selects setpoint color switch 104 to carry out brush color setting, and user's touching is by mobile drawing after the completion of setting
Drawing switch 107 on device 100, finger can form drawing when moving on touch screen 200 on touch screen 200 at this time
Lines.User can touch by the rubber switch 106 on mobile picture-drawing device 100, at this time finger when being moved on touch screen 200,
The intersection of the lines intersected with motion track can be wiped.I.e. touch screen 200 detects the location of pixels that user's finger touches,
If the position, which exists, has been displayed pixel, by pixel value zero (default painting canvas pixel value can also be classified as).If user is not
Any switch is pressed in touching, then is touch mode at this time, and user can touch the lines once drawn with finger, when user's finger is mobile
When lines on track and touch screen 200 intersect, i.e., touch screen 200 detects the location of pixels that user's finger touches, if the position
In the presence of pixel has been displayed, then the color of the pixel is sent to processor 600 by touch screen 200, and processor 600 is according to above-mentioned face
Color, drive the speaker 700 issue the sound of corresponding tone.Touch screen 200 detects the location of pixels that user's finger touches, if the position
It sets there is no pixel has been displayed, then 600 mute speaker of processor, 700 sounding.That is, 700 phonation time of loudspeaker takes
The time to have drawn lines is certainly touched in finger.The corresponding relationship of above-mentioned color and tone is as follows:
| Color | It is black | It is red | It is yellow | It is green | It is blue | It is purple | It is white |
| Tone | Dou | Ruai | Mi | Fa | Sou | La | Xi |
Certainly, the corresponding relationship of color and tone can also be set by user.Such as Dou corresponds to brown etc..Meanwhile
User can also carry out colour mixture according to the color on above-mentioned basis.The method of colour mixture are as follows: K1 × P1+K2 × P2 represents K1 parts of C1 and K2
Part C2 mixing.Wherein K is beat, such as K1=1/4, K2=1/2；P represents tone, such as P1=Ruai, P2=Mi；It is corresponding that C represents P
Color, such as C1 represents red, and C2 represents Huang.Therefore, above-mentioned colour mixture is that 1/4 part of red is mixed in proportion with 1/2 yellow
The color obtained afterwards, i.e., more partially more yellow is orange.And the corresponding sound of the color be 1/4 bat Ruai and 1/2 clap Mi successively into
What row sounding was formed.The essence of beat is the ratio of time, can also replace beat with the various times, such as press 0.25s
Ruai and 0.5s Mi, corresponding color blending effect are same as described above.It is more flexible come each color-ratio of colour mixture with the time, but
There is a problem of it is more chaotic, and beat be also it is common in music, be easier to receive with the mode of beat and of the invention
One of inventive point.
Color switch 104 on mobile picture-drawing device 100 shares 8, and first 7 respectively correspond 7 kinds of colors of user preset
Paintbrush, the 8th can be set by the user for commonly use color.If user needs to carry out colour mixture, 7 are consecutively pressed by beat
2 or multiple in switch.Such as it is above-mentioned press the bat of 1/4 bat Ruai and 1/2 Mi then paintbrush become orange (partially yellow) at this time, with
When family is arranged, processor 600 is according to the corresponding tone for issuing corresponding beat of switch control loudspeaker 700 that user presses.In this way,
User can need to set according to oneself primary colours in 7, and can carry out colour mixture according to primary colours, and can pass through the difference of sound
It distinguishes.User completes the setting of colour mixture at this time, is carrying out after consecutively pressing 2 or multiple in 7 switches by beat
It also needs to touch by special drawing switch 107 when drawing.
The system of existing painting from Blind Persons usually uses for reference braille system, is felt with the tactile of the lines excitation blind person of protrusion
Know.But this system can not embody the variation of color.It is difficult to realize to have the convex of sense of touch simultaneously when being drawn a picture on electronic curtain
Lines out.And if drawn a picture with the nose line material of conventional dedicated, and it cannot achieve electronization, it just can not be automatically to blind
The achievement of people's drawing carries out evaluation feedback.But in fact, blind person is other than sense of touch is sensitive, hearing is also very sharp.Present invention wound
Color is replaced to the property made using different tones, solves the defect of blind person's Color perception, blind person is allowed to learn to complete face
The colourful paint of color.Meanwhile when carrying out drawing study on electronic curtain, the sound sense of different tones can be passed through
Know the lines on screen, convenient for positioning completed lines, forms drawing feedback.
For some blind users, there are obstacles, such as congenital blindness never to have is understood to the Plane performance of object
The blind person of chance trial painting.Although they can touch the object in the existing world with hand, can not be envisioned as how
It goes to show with plane lines.And object (such as emerging object after its blindness) such as fruit volume that blind person is unknown is larger, blind person
It only is difficult to accurately recognize the object by both hands touch, just it is even more impossible to paint.Therefore need to set the step of drawing training
Carry out drawing study.
Training painting mode:
Various paints are stored in memory 500, for example including personage, landscape, still life etc., can according to need into
Row downloading deposit, can also be shared by other blind users into the memory 500 of user.Paint can be carried out by difficulty
Classification.Processor 600 reads a wherein width works, and according to the label of the works, drive the speaker 700 informs user's drawing
The main contents of works.By taking simple picture " people " as an example, the informing of loudspeaker 700 user " this time training content is simple picture ---
People ".Painting order of the processor 600 built according to the works, paints since head.The coordinate of read head starting point, driving
Mobile picture-drawing device 100 is moved to the starting point, moves the gripping of picture-drawing device 100 user hand at this time and moves together, loudspeaker 700 is logical
Know user " starting picture head portion at this time ".Processor 600 obtains the coordinate value of each point on the lines of works head, drives mobile drawing
Device 100 is successively moved, and the movement of drawing is simulated.After completing contouring head, processor 600 reads rising for works ear
Point coordinate drives mobile picture-drawing device 100 to be moved to the starting point, and loudspeaker 700 notifies user " starting picture ear at this time " at this time,
Processor 600 obtains the coordinate value of each point on works ear lines, drives mobile picture-drawing device 100 successively to be moved, mould
The movement of quasi- drawing.And so on, complete entire paint.In this process, mobile picture-drawing device 100 leads user hand
Carried out the operation of entire drawing, not only allowed a user knowledge of the drawing method of the works, and make user for " people " this
The laid out flat mode of one larger object has intuitive understanding.
In fact, much blind persons are due to the not concept of laid out flat and correctly feedback, for thousand surprise hundred of the technique of painting of " people "
Strange or even some details are beyond expression.As shown in the left side Fig. 3, the user of congenital blindness is according to " people " of oneself everyday exposure
Once attempt the pattern painted.It is since user does not know how that according to user feedback, in figure, people, which does not have face,
The eyes in different depth position, ear, mouth, nose etc. are drawn in plane.Moreover, drawing is great for blind person
Psychology challenge, it is difficult to calm completion.
Assist painting mode:
After completing training, user can remember to draw to having had whole understanding in being learnt by multipass training
The lines and step of picture can enter auxiliary painting mode after this.
In this mode, the hand of user's drawing is held by moving picture-drawing device 100, user according to content trained before,
With the memory of oneself and the mobile finger of feeling.User's finger is set out from starting point (x0, y0), and user hand is to mobile picture-drawing device at this time
100 driving force is by moving the detection of two force snesors on picture-drawing device 100.Wherein X, Y-direction the obtained power of sensor
Respectively Ux, Uy.Processor 600 calculates the direction that mobile picture-drawing device 100 will move according to the size of Ux, Uy, i.e., under
The position (x1, y1) of one stepped intervals target point.Meanwhile processor 600 obtains the coordinate of next stepping point on the painting
(x2, y2).If | x2-x1 |/| x2-x0 | < m, and | y2-y1 |/| y2-y0 | < m then moves picture-drawing device 100 with user hand one
It rises and is moved to the point (x2, y2), if being unsatisfactory for any one above-mentioned condition, move picture-drawing device 100 and lock, prevent user hand
It is mobile, while loudspeaker 700 uses unique auditory tone cues user, guarantee that track that user hand moves and works content are basic in this way
Unanimously.According to experiment, step distance is usually 1-5mm, and threshold value m is 0.1-0.4.It can be gradually reduced according to user's qualification
Step distance and threshold value.
Free painting mode:
After user completes auxiliary painting mode, it can be can according to need with freedom of entry painting mode, user by above-mentioned
Method preset color also can choose currently used color.User can also be touched with hand according to the above method and drawn
Content, stripe shape is judged by the prompt tone of loudspeaker 700, to form the feedback of similar vision, understanding has been painted
Lines.And next step drawing is carried out according to above content.Certainly, it staggers the time in picture, user can also use according to the above method
The tools such as rubber.After user completes drawing, processor 600 receives the information on touch screen 200, by picture data and user hand
Refer to that mobile position and alphabetic data are stored in memory 500.Picture data is transmitted to 3D printing processing module simultaneously, and
The printing of 3D picture is carried out according to picture data by 3D printer 800, that is, selects the 3D material with picture lines corresponding color, it will
It is printed upon on drawing board by lines location, forms certain lines protrusion.After completing printing, which appreciates for blind person and handing over
Stream can feed back mutually pictorial skill, and it is horizontal to improve drawing.Therefore by the electronic painting utilization of works 3D printer of conventional planar
Carrying out printing is also one of inventive point of the invention.
By above three mode step, blind person usually can simply be painted.As shown in figure 3, the left side be without
Paint when training is crossed, and the right is the training Jing Guo an above three step respectively, obtained works.As it can be seen that drawing
Picture level has been enhanced.If it is intended to carrying out more complicated drawing, need constantly to carry out using above system
Training, while highly difficult works constantly being selected to be imitated.By the experiment of 13 blind persons, longest can be completed by 1 year
The drawing independently created.
In order to guarantee trained accuracy, need often to be corrected mobile picture-drawing device 100.Such as start in training
Before, set starting point A(X0, Y0), set terminal B(X1, Y1), mould is damped using X, Y both direction in mobile picture-drawing device 100
Block, the influence mobile for mobile picture-drawing device 100 of simulation manpower, the final shift position of manipulator is (X2, Y2), correction coefficient
For △ X=| X2-X1 |/| X1-X0 |, △ Y=| Y2-Y1 |/| Y1-Y0 |.
There is X, Y both direction force snesor on mobile picture-drawing device 100, in a preceding training mode, mobile drawing
